In the past decade the question has been raised, at IAU meetings, as to whether more asteroids should be discovered, and the answer now is: “Yes, indeed, do discover as many comets and asteroids as possible.” Marsden gives strong encouragement to search for “lost” comets and asteroids. The more ephemerides known the better physical and statistical studies we can make. We have completion of the asteroids now to about 14 mag. With existing patrol instruments of about 25 cm opening, for instance at Indiana and in South Africa, the limiting magnitude for an extended program is about 16.

South Africa today faces both increasingly radical calls for systemic change from various sectors, and apparently intransigent organisational cultures whose performance in delivering racial “transformation” and equality in the workplace has been extremely disappointing. It is argued that a different way of managing organisations is possible, but that this requires both a commitment to a new set of values, and the possession of the skills to deal with difference, which are summarised as critical diversity literacy (CDL). In order to improve CDL capacity within organisations, baseline measurements are necessary to tailor interventions and to track progress. We propose a preliminary metric based on data gathered from practical interventions, including leadership interviews in a large national organisation, that revolve around five thematic hooks: (1) society at large, (2) the organisation’s understanding of the past, (3) ideologies around change, (4) apportioning of responsibility, and (5) the conception of difference. Ways of identifying capacity (positive scripts) or lack thereof (negative scripts) are proposed and discussed as a preface to future work on deepening and refining the model.

This study sought to assess the extent of research collaboration in Library and Information Science (LIS) schools in South Africa between 1991 and 2012. Informetric research techniques were used to obtain relevant data for the study. The data was extracted from two EBSCO-hosted databases, namely, Library and Information Science Source (LISS) and Library, Information Science and Technology Abstracts (LISTA). The search was limited to scholarly peer reviewed articles published between 1991 and 2012. The data was analysed using Microsoft Excel ©2010 and UCINET for Windows ©2002 software packages. The findings revealed that research collaboration in LIS schools in South Africa has increased over the past two decades and mainly occurred between colleagues from the same department and institution; there were also collaborative activities at other levels, such as inter-institutional and inter-country, although to a limited extent; differences were noticeable when ranking authors according to different computations of their collaborative contributions; and educator-practitioner collaboration was rare. Several conclusions and recommendations based on the findings are offered in the article.

Dullstroom-Emnotweni is the highest town in South Africa. Cold and misty, it is situated in the eastern Highveld, halfway between the capital Pretoria/Tswane and the Mozambique border. Alongside the main road of the white town, 27 restaurants provide entertainment to tourists on their way to Mozambique or the Kruger National Park. The inhabitants of the black township, Sakhelwe, are remnants of the Southern Ndebele who have lost their land a century ago in wars against the whites. They are mainly dependent on employment as cleaners and waitresses in the still predominantly white town. Three white people from the white town and three black people from the township have been interviewed on their views whether democracy has brought changes to this society during the past 20 years. Answers cover a wide range of views. Gratitude is expressed that women are now safer and HIV treatment available. However, unemployment and poverty persist in a community that nevertheless shows resilience and feeds on hope. While the first part of this article relates the interviews, the final part identifies from them the discourses that keep the black and white communities from forming a group identity that is based on equality and human dignity as the values of democracy.

Background:Poor medical waste management has been implicated in an increase in the number of epidemics and waste-related diseases in the past years. South Africa is resource-constrained in the management of medical waste.Objectives:A review of studies regarding medical waste management in South Africa in the past decade was undertaken to explore the practices of medical waste management and the challenges being faced by stakeholders.Method:Published articles, South African government documents, reports of hospital surveys, unpublished theses and dissertations were consulted, analysed and synthesised. The studies employed quantitative, qualitative and mixed research methods and documented comparable results from all provinces.Results:The absence of a national policy to guide the medical waste management practice in the provinces was identified as the principal problem. Poor practices were reported across the country from the point of medical waste generation to disposal, as well as non-enforcement of guidelines in the provinces where they exit. The authorized disposal sites nationally are currently unable to cope with the enormous amount of the medical waste being generated and illegal dumping of the waste in unapproved sites have been reported. The challenges range from lack of adequate facilities for temporary storage of waste to final disposal.Conclusion:These challenges must be addressed and the practices corrected to forestall the adverse effects of poorly managed medical waste on the country. There is a need to develop a medical waste policy to assist in the management of such waste.

Investigating the role of physiology in communication research is a burgeoning area of study that has gained considerable attention by relational scholars in the past decade. Unfortunately, very few published studies on this topic have evoked important questions about the role of race and ethnicity. Exploring issues of ethnicity and race provides a more holistic and inclusive view of interpersonal communication across diverse groups and communities. This chapter addresses the gap in literature by considering the ways in which race and ethnicity matter in work on physiology and interpersonal interactions. More specifically, this chapter will first discuss the conceptual underpinnings of race, ethnicity, and other relevant concepts and then review extant research within and beyond the field of communication on race, ethnicity, interpersonal interactions, and physiology. These discussions set the foundation for this chapter to propose new lines of research that pointedly connect these four concepts and advance key principles that scholars should consider in future work.

Twenty paired 14C and U/Th dates covering most of the past 50,000 yr have been obtained on a stalagmite from the Cango Caves in South Africa as well as some additional age-pairs on two stalagmites from Tasmania that partially fill a gap between 7 ka and 17 ka ago. After allowance is made for the initial apparent 14C ages, the age-pairs between 7 ka and 20 ka show satisfactory agreement with the coral data of Bard et al. (1990, 1993). The results for the Cango stalagmite between 25 ka and 50 ka show the 14C dates to be substantially younger than the U/Th dates except at 49 ka and 29 ka, where near correspondence occurs. The discrepancies may be explained by variations in 14C production caused by changes in the magnetic dipole field of the Earth. A tentative calibration curve for this period is offered.

AbstractThis paper presents a report on outcomes of the 10th Computational Modeling in Biology Network (COMBINE) meeting that was held in Heidelberg, Germany, in July of 2019. The annual event brings together researchers, biocurators and software engineers to present recent results and discuss future work in the area of standards for systems and synthetic biology. The COMBINE initiative coordinates the development of various community standards and formats for computational models in the life sciences. Over the past 10 years, COMBINE has brought together standard communities that have further developed and harmonized their standards for better interoperability of models and data. COMBINE 2019 was co-located with a stakeholder workshop of the European EU-STANDS4PM initiative that aims at harmonized data and model standardization for in silico models in the field of personalized medicine, as well as with the FAIRDOM PALs meeting to discuss findable, accessible, interoperable and reusable (FAIR) data sharing. This report briefly describes the work discussed in invited and contributed talks as well as during breakout sessions. It also highlights recent advancements in data, model, and annotation standardization efforts. Finally, this report concludes with some challenges and opportunities that this community will face during the next 10 years.

Abstract Hearing Loss (HL) is common among older adults and is associated with poor health care quality outcomes include 30-day readmissions, length of stay, poorer satisfaction, and increased medical expenditures. These associations may manifest in changes in help-seeking behaviour. In the 2015 Current Medicare Beneficiary Study (MCBS) (n=10848; weighted sample=46.3 million), participants reported whether they knowingly had avoided seeking care in the past year and self-reported HL was measured as degree of trouble (none, a little, or a lot) hearing when using a hearing aid if applicable. In a model adjusted for demographic, socioeconomic, and health factors, those with a little trouble (OR= 1.612; 95% CI= 1.334-1.947; P<0.001) and a lot of trouble hearing (OR= 2.011; 95% CI= 1.443-2.801; P<0.001) had 61.2% and 101.1% higher odds of avoiding health care over the past year relative to participants with no trouble hearing. Future work should examine whether hearing care modifies this association.

The Market Theatre of Johannesburg opened in 1976, the year of the Soweto Uprising – the beginning of the end for the oppressive apartheid regime. Founded by Barney Simon, Mannie Manim, and a group of white actors, the theatre's policy, in line with the advice to white liberals from the Black Consciousness Movement, was to raise the awareness of its mainly white audiences about the oppression of apartheid and their own social, political, and economic privileges. The theatre went on through the late 'seventies and 'eighties to attract international acclaim for productions developed in collaboration with black artists that reflected the struggle against the incumbent regime, including such classics as The Island, Sizwe Bansi is Dead, and Woza Albert! How has the Market fared with the emergence of the new South Africa in the 'nineties? Has it built on the past? Has it reflected the changes? What is happening at the theatre today? Actress, writer, and director Hilary Burns went to Johannesburg in November 2000 to find out. She worked in various departments of the theatre, attended productions, and interviewed theatre artists and members of the audience. This article will form part of her book, The Cultural Precinct, inspired by this experience to explore how the theatres born in the protest era have responded to the challenges of the new society.

Early in 1959, observations on the farm Tayside, in the East London district of South Africa, suggested that populations of the ‘two-host’ red tick, Rhipicephalns evertsi Neum., were more difficult to control with toxaphene preparations than they had been in the past. Resistance to toxaphene was suspected, and both field and laboratory experiments were carried out to investigate this possibility. Field trials indicated an increase in tolerance by Tayside populations of the tick to toxaphene, γ BHC and dieldrin, but showed no increased tolerance to sodium arsenite or DDT. Similar results were obtained in laboratory experiments where Tayside adults were compared with those of other populations of the tick known to be sensitive to insecticides. Laboratory experiments with larvae indicated a high degree of resistance to toxaphene and γ BHC in the Tayside population, but no increased tolerance to sodium arsenite, Delnav, Sevin or DDT could be detected. This pattern of cross-resistance is similar to that occurring in resistant populations of Boophilus dccoloratus(Koch).
